95 Contour SE Engine Light

I have been driving this Contour for about 3 years now, and have always dealt with the _Engine Light_ coming on from time to time. Most generally I haven't payed much mind to it since it had only came on when ascending or descending (up or down hills). I had rencently given the car it's winter spark plugs and air/fuel filters, and now the light comes on more often.
I checked the codes today, and they are these:
117 - Engine Coolant Temp sensor circuit below minimum voltage / 254deg indicated
217 - PCM detected coil 3 primary circuit failure (EI)
617 - 1 - 2 Shift error

I know the definitions for the codes from my Chilton Manual, but I am unsure of what the cause would be. The engine runs great; Transmission was replaced at 70,000 miles (has 112,000 now); everything else is completely stock on the car.

If anyone has any advice, I can fix almost anything that is necessary, finances allowing anyway.

Thank You

Probably crud has build up on the Coolant temperature sensor. When was the last time you have a coolant flush? The coolant temperature sensor might just need to be cleaned and see what happens.

I should mention also that the Coil Pack is less than a year old. I was reading the same codes with the stock original coil pack and thought that replacing it would solve that problem.

As far as I can tell by looking at the coolant reservoir, it's the most perfect shade of green. No rust or oily look or texture. I let the car warm up to normal operating temparature before reading the trouble codes. I am thinking that the sensor will just have to be replaced.

My '95 has had the same problem for a year, sometimes the low coolant level light comes on as well. Engine runs great, and coolant is clean and green in the tank. I'm not planning on changing the sensor.

this year contour had a recall for the entie underhood wiring harness-mutiple wiring problems;think the recall was 10 year/100,000 mile coverage

Is that the '95 model year that you are talking about??? I have to say though that I am over 112000 miles on this thing. It's gonna become a soon-to-be trade-in. Unless I can find someone to buy it from me when it's time to get a new car.

I was also wondering if anyone knew where I could get plugs for the wiring harness??? I would like to replace several sensor plugs and the coil pack plug. I guess I mean, pig tails that I can cut and splice onto the original wiring, I think that there may be a broken wire on a few of the sensors, as with most Ford's, the wire coverings are dry and brittle and bare wire showing.
